libstdc++: Avoid some more warnings [PR104019]

With -fno-exceptions we get a -Wmisleading-indentation warning for:

  if (cond)
    __try {}
    __catch (...) {}

This is because the __catch(...) expands to if (false), but is indented
as though it is controlled by the preceding 'if'. Surround it in braces.

The new make_shared<T[]> code triggers a bogus warning due to PR 61596,
which can be disabled with a pragma.

libstdc++-v3/ChangeLog:

	PR libstdc++/104019
	* include/bits/istream.tcc (basic_istream::sentry): Add braces
	around try-block.
	* include/bits/shared_ptr_base.h (_Sp_counted_array_base::_M_init):
	Add pragmas to disable bogus warnings from PR 61596.
